1 089,571 Specification of Letters Patent. 10 1914 the level body and intermediate its edges, I secure bearing plates 6 to the body of the level by any suitable means, as for instance, by the pins 7 inserted through apertures formed in the bearing plates and in the level body, and having their ends upset agamst said plates and level body to secure said plates firmly to the body of the level.

hese bearing plates 6 are preferably provided with a boss 8 and with an internally threaded aperture extending therethrough. The outer face of the boss 8 terminates preferably at a point within the plane of the outer edges of the body of the level. A timber engaging device is provided in the form of a threaded pin 11 having a milled head 12 and formed adjacent its outer end with a shoulder 13 from which point the pin is reduced and extends outwardly to a point. The pin 11 is inserted from the side of the level body opposite a bearing plate 6 through a bore formed in said level body in alinement with the threaded bore of the bearing plate, the screw threads thereof, cooperating with said threaded bore and being adapted to move the pin within said bore to bring its pointed end into holding engagement with woodwork to which the level is applied. These pins 11 are preferably moved up to bring their shoulders 13 against the face of the timber engaged by their points, to utilize said shoulder as a bearing face. It will be evident therefore, that with a level of the type described, provided with such holding devices an operator may place such a level against timber and by means of the level glasses thereon adjust the level to the desired position. The pointed pins 11, may then be turned by the operator to move their points 14 into holding engagement with the timber, the level body being pressed against the timber with one hand, while the pin is being operated with the other, and the points 14 of the pin serving to retain the level body in proper position against the timber. The operator may then readily hold the level against the timber with one hand while with the other he moves a scratch awl or other markin implement along the straight edge of the level in the usual manner.

The threaded bore of each bearing plate with which the threaded pins 11 cooperate, is of substantial length, affording a long To all whomz't may concern Be it known that THOMAS H. MoNUTr, deceased, late a citizen of the United States and resident of Pine Bluff, in the county of Jefferson, State of Arkansas, did invent new and useful Improvements in Levels, of which the following is a full, clear, and exact description. V

This invention relates to improvements in levels and is more especially designed to pro-- vide means whereby the level may be readily held in adjusted position by the operator, while a scratch awl or other marking device is drawn along the straight edge of the level. This and other advantages are described n detail in the following specification taken in connection with the accompanying drawlngs forming part thereof and illustrating a preferable embodiment of the invention.

In these drawings Figure 1 is a view in side elevation of a level embodying the invention. Fig. 2 is a fragmentary view of one end of the level with one of the holding devices applied thereto. Fig. 3 is a similar view of the opposite face of the level. Fig. 4 is a vertical section through the level'taken on the line 44 of Fig. 3. Fig. 5 is a view in end and side elevation showing the holding point, and Fig. 6 is a detail view in front and edge elevation of the bearing plate cooperating therewith.

Referring to the drawings by numerals, 1 indicates, generically, the body of a metal level provided with the parallel straight edges 2 extending longitudinally thereof and provided with straight edges 3 at its ends. The body of the level is preferably recessed to receive level glasses 4: extending transversely thereof and both facing in opposite direction, so that both levels may be viewed by the operator in plumbing down a joist underneath a floor, for instance. The level also preferably has its body recessed to receive a third level glass 5 extending longitudinally of the level body. In scribing or otherwise marking a line upon woodwork along one of the straight edges 2 of this level, it is very difficult for the operator to hold the level and to also handle a scratch awl or other tool at the same time. This invention provides means whereby this may be readily accomplished, these means preferably taking the following form.

At a plurality of points longitudinally of bearing for its threaded pin, the bearing the indentations made by their points may plate being preferably of a thickness which be utilized i0;- n arlging and indicating purwill brin it somewhat within the plane of poses without t 1 V neeessity of using a the side earings of the level body.

Hence, when thereof, the overall length of said pins not the point 14 s retired to the inoperative .poexceeding the thickness of the sition, he level body can be placed flatwise body, with means for projecting said pins with its side bearings properly engaging with so that they will extend slightly beyond one 20 a flat piece of timber, Whereas if the length side bearing face of said level body and of the screw with its point and head ,exfor retiring said pins so that both ends ceeded the maximum thickness of the level thereof will not project beyond the opposite body one end or the other would project at side bearing surfaces. 7 all times making it impossible to get a true ANNA ELEANOR M NUTT, 1 bearing of the level body against a flatild'ministmtra: of fhomas H.
